I can't find anything I can make heads or tails out of so if you guys can help I thank you. I would like to design a wind turbine and be able to get as much power as I can out of each of it's coils. If I start with a magnet that is 1.1811" in Diameter and it is .125" thick with a grade of N52 and I only allow for a air space of .0625" between the magnets and coils what would be the ideal coil size / wire gauge to use and so forth. I can't find the exact specs for that particular magnet but from looking at another very similar one the spc's for the magnet would be approximately as follows; N52 Br: >=14,800 Gauss Bhmax: 52MGOe Surface Field: 918 Gauss Given I make the inside of the coil the diameter 1.1811", (the diameter of the magnet) what are the other specs I should use to make the coils if I want it to generate power at a low wind speed. I'm thinking it would not be able to go much faster then 300rpm. (my best guess) So in other words how many loops across should I go with the coil and how many layers of coils should I go and with what gauge of wire. Also given 300rpm how many volts / amps / watts would the finished coil put out. Thanks and sorry if I'm missing something here, I'm no physics expert by any means.
